In the description of the present invention, the meaning of "a plurality of" is two or more unless otherwise specifically defined.
[0035] Please refer toFigures 1 to 11 , the explosion-proof man-machine interaction device provided by the present invention will be described. The explosion-proof man-machine interaction device for mines includes a control box 1, an emergency stop button device 2, a regulation button device 3, and a controller. An explosion-proof plate 11 is provided inside the control box 1, and the explosion-proof plate 11 is used to divide the interior of the control box 1 into a first chamber 12 and a second chamber 13. The controller is electrically connected to the emergency stop button device 2, the regulation button device 3, and the execution device respectively;
[0036] The emergency stop button device 2 includes a sliding component 21, a first sensor 22, and an emergency stop component 23. The sliding component 21 and the first sensor 22 are arranged in the first chamber 12, and the emergency stop component 23 penetrates through the side wall of the control box 1 and extends into the second chamber 13. The emergency stop component 23 can magnetically adsorb the sliding component 21 to move away from the first sensor 22. The first sensor 22 is used to detect the sliding component 21 to generate a first proximity information and send the first proximity information to the controller;
[0037] The regulation button device 3 includes an elastic button 31, a control magnetic part 32, and a Hall sensor 33. The elastic button 31 penetrates through the side wall of the control box 1 and extends into the second chamber 13. The control magnetic part 32 is connected to one end of the elastic button 31 close to the explosion-proof plate 11. The Hall sensor 33 is arranged in the first chamber 12. The control magnetic part 32 can be driven by the elastic button 31 to approach the Hall sensor 33. The Hall sensor 33 is used to generate a Hall signal and send it to the controller.
[0038] Compared with the prior art, the explosion-proof man-machine interaction device for mines provided in this embodiment divides its inner cavity into a first chamber 12 and a second chamber 13 by arranging an explosion-proof plate 11 inside the control box 1. The sliding component 21 and the first sensor 22 of the emergency stop button device 2 are arranged in the first chamber 12, the emergency stop component 23 is arranged in the second chamber 13, the Hall sensor 33 of the regulation button device 3 is arranged in the first chamber 12, and the elastic button 31 and the control magnetic part 32 are arranged in the second chamber 13. It can realize the cavity separation design, meet the sealing performance of the second chamber 13, and further ensure the reliable operation of the electrical components in the first chamber 12, improving the safety and convenience of man-machine interaction. At the same time, by driving the control magnetic part 32 to approach the Hall sensor 33 by the elastic button 31, the controller can receive the Hall signal and control the speed of the execution device, improving the man-machine interaction performance of the device.
[0039] For the convenience of description, the end of the sliding component 21 and the emergency stop component 23 close to the explosion-proof plate 11 is defined as the inner end, and the end far from the explosion-proof plate 11 is defined as the outer end. At the same time, the end of the elastic button 31 close to the explosion-proof plate 11 is defined as the inner end, and the end far from the explosion-proof plate 11 is defined as the outer end.
[0040] In this embodiment, for the convenience of structural installation, the control box 1 is in the form of two parts on the left and right being joined together to form an inner cavity for installing electrical components. The explosion-proof plate 11 divides the inner cavity of the control box 1 into a first chamber 12 and a second chamber 13 that are isolated from each other. The first chamber 12 and the second chamber 13 can be isolated from each other and sealed separately by means of setting a sealing ring 46 or filling sealant around the outer circle of the explosion-proof plate 11. Specifically, the explosion-proof plate 11 can be made of explosion-proof glass, which has a good explosion-proof effect and can meet the explosion-proof performance under the mining conditions.
[0041] When operating the emergency stop button device 2 or the regulation button device 3, only the parts of the two devices located in the second chamber 13 are operated, and water will not enter the first chamber 12. Furthermore, the normal operation of other electrical components in the first chamber 12 can be ensured, and the safety and stability of the equipment operation can be improved.
[0042] It should be noted that the Hall sensor 33 is a magnetic field sensor made according to the Hall effect. The Hall effect sensor is a transducer that converts a changing magnetic field into a change in the output voltage.
[0043] Specifically, during the normal use of the equipment, by pressing the elastic button 31 to drive the control magnetic part 32 to move closer to the Hall sensor 33, different magnetic fields are formed according to the different pressing depths of the elastic button 31. Furthermore, the Hall sensor 33 generates different Hall signals. After receiving the Hall signals, the controller sends corresponding control instructions to the execution device to effectively control parameters such as the speed of the execution device.
[0044] When an emergency occurs and an emergency stop is required, press the emergency stop component 23 of the emergency stop button device 2. The emergency stop component 23 moves towards the side close to the sliding component 21, forming an adsorption effect on the sliding component 21. Furthermore, the sliding component 21 moves away from the first sensor 22, and the first sensor 22 stops sending the first proximity signal to the controller. The controller can judge according to the preset program that an emergency stop process is required, and then send an emergency stop instruction to the execution device to achieve the emergency stop operation of the equipment.
[0045] In a possible implementation manner, please refer to Figures 1 to 11 , the sliding component 21 includes a sliding rod 211, a first elastic member 212 and a first magnetic member 213. The sliding rod 211 is arranged in the first chamber 12 and is arranged at an angle with the explosion-proof plate 11. The first magnetic member 213 is connected to the inner end of the sliding rod 211. The first sensor 22 is connected in the first chamber 12 and is located at the outer end of the sliding rod 211. The first elastic member 212 is connected in the first chamber 12 and is used to elastically push the sliding rod 211 outward to be in contact with the first sensor 22;
[0046] The emergency stop assembly 23 includes a mounting base 231, an emergency stop lever 232, a second magnetic member 233, and an elastic snap ball 234. The mounting base 231 is connected inside the second chamber 13 and is coaxially arranged with the sliding rod 211. The emergency stop lever 232 penetrates through the mounting base 231 and is slidably engaged with the mounting base 231. The second magnetic member 233 is connected to the inner end of the emergency stop lever 232 and is used to adsorb the first magnetic member 213 to move the sliding rod 211 away from the first sensor 22. Axially spaced first and second card slots 235 and 236 are provided on the peripheral wall of the emergency stop lever 232. The elastic snap ball 234 is embedded in the inner peripheral wall of the mounting base 231 and is used to elastically snap into the first card slot 235 or the second card slot 236.
[0047] In this embodiment, the first elastic member 212 of the sliding assembly 21 can elastically push the sliding rod 211 to a position close to the first sensor 22, so that the first sensor 22 can monitor the sliding rod 211 to feedback a first proximity signal to the controller, and the controller controls the actuating device to maintain the connected state according to the preset program.
[0048] When an emergency stop operation is required, pressing the emergency stop lever 232 drives the second magnetic member 233 to approach the explosion-proof plate 11 and adsorb the first magnetic member 213. Then, the first magnetic member 213 is used to drive the sliding rod 211 away from the first sensor 22. At this time, the first sensor 22 cannot generate a first proximity signal, and the controller determines according to the preset program that it is necessary to control the disconnection of the actuating device, thereby achieving the emergency stop effect.
[0049] When pushing the sliding rod 211, the elastic snap ball 234 provided on the mounting base 231 can snap into the first card slot 235 or the second card slot 236 to realize the axial position limit of the sliding rod 211. The first card slot 235 can correspond to the position where the sliding rod 211 is close to the explosion-proof plate 11 and the second magnetic member 233 can adsorb the first magnetic member 213. The second card slot 236 can correspond to the position where the sliding rod 211 is away from the explosion-proof plate 11 and the second magnetic member 233 and the first magnetic member 213 are separated from each other.
[0050] In a possible implementation, please refer to Figures 1 to 11 , the sliding assembly 21 further includes a connection seat 214 connected inside the first chamber 12. The sliding rod 211 penetrates through the connection seat 214 and is slidably engaged with the connection seat 214. The first sensor 22 is connected to the outside of the connection seat 214.
[0051] In this embodiment, the setting of the connection seat 214 facilitates the installation of components such as the sliding rod 211. The connection seat 214 is connected to the inner top wall of the first chamber 12. The sliding rod 211 is slidably connected to the connection seat 214. The main axis of the sliding rod 211 can be perpendicular to the explosion-proof plate 11, which is convenient for ensuring the adsorption effect of the second magnetic member 233 on the first magnetic member 213.
[0052] Meanwhile, the first sensor 22 is connected to the outside of the connection base 214, that is, the side of the connection base 214 away from the explosion-proof plate 11. Under the pushing action of the first elastic member 212, the sliding rod 211 can maintain a state adjacent to the sensor, so that the first sensor 22 can detect the outer end of the sliding rod 211 to form a first proximity signal and send it to the controller. The controller makes a determination according to the preset program and controls the actuator to be in a normal operating state.
[0053] In some embodiments, please refer to Figures 1 to 11 , a small-diameter end 215 for installing the first magnetic member 213 is provided at the inner end of the sliding rod 211, and a plurality of first magnetic members 213 are arranged in sequence along the axial direction of the small-diameter end 215; a first spacer 216 is sleeved on the sliding rod 211 between the connection base 214 and the first magnetic member 213, and a limit snap ring 217 for limiting the axial position of the first magnetic member 213 is clamped on the outer periphery of the small-diameter end 215.
[0054] In this embodiment, by providing a first hole 218 and a second hole 219 with different aperture sizes on the connection base 214, the aperture of the first hole 218 is larger than the space of the second hole 219. The first hole 218 is located on the end face of the connection base 214 close to the first sensor 22. The first hole 218 and the second hole 219 respectively effectively limit the positions of the limiting plate 2111 and the first elastic member 212. A limiting plate 2111 slidably connected to the first hole 218 is provided at the outer end of the sliding rod 211, and the sliding amplitude of the sliding rod 211 is limited by the first hole 218.
[0055] When the second magnetic member 233 adsorbs the first magnetic member 213, the first elastic member 212 is compressed under the limiting action of the bottom wall of the second hole 219, and the sliding rod 211 stops after moving away a certain distance. At this time, the first sensor 22 is away from the sliding rod 211. When the device returns to normal, the emergency stop lever 232 moves to the side away from the explosion-proof plate 11, and the elastic ball 234 is clamped in the first card slot 235. The second magnetic member 233 loses the adsorption effect on the first magnetic member 213, and the sliding rod 211 can move to the side away from the explosion-proof plate 11 under the action of the first elastic member 212, so that the first sensor 22 can detect the sliding rod 211, and then send a first proximity signal to the controller, so that the controller controls the actuator and enables the device to operate normally.
[0056] In order to prevent the adsorption between the first magnetic member 213 and the connection base 214, a first spacer 216 is provided between them. The first spacer 216 is made of a non-magnetic material, which can prevent the interaction between the first magnetic member 213 and the connection base 214, and thus ensure the effective adsorption of the second magnetic member 233 on the first magnetic member 213 during emergency stop.
[0057] On this basis, the mounting seat 231 is connected to the control box 1 through the first connecting member 238. The first connecting member 238 can be set to a plurality of and are arranged at intervals in the circumferential direction of the mounting seat 231. Specifically, three, four or five can be set, which can ensure the reliable connection between the mounting seat 231 and the control box 1.
[0058] Furthermore, an emergency stop button 239 can be provided at the outer end of the emergency stop lever 232. The cross-sectional area of the emergency stop button 239 is larger than that of the emergency stop lever 232, which is convenient for manual pressing operation and ensures the effectiveness of the emergency stop action.
[0059] In a possible implementation manner, please refer to Figures 1 to 11 , a radially penetrating radial hole 237 is provided on the mounting seat 231. The elastic clamping ball 234 includes a plug 2341, a second elastic member 2342 and a sphere 2343. The plug 2341 is in threaded cooperation with the radial hole 237 and is located at the outer end of the radial hole 237. The second elastic member 2342 is connected to the inner end of the plug 2341, and the sphere 2343 is connected to the inner end of the second elastic member 2342. The sphere 2343 is used for clamping in the first clamping groove 235 or the second clamping groove 236.
[0060] In this embodiment, at least two groups of elastic clamping balls 234 are provided to axially limit the emergency stop lever 232 at different positions in the circumferential direction of the mounting seat 231. The second clamping groove 236 is provided on the side of the first clamping groove 235 away from the explosion-proof plate 11. When the elastic clamping ball 234 is clamped in the first clamping groove 235, the device is in a normal operating state. When the emergency stop lever 232 is manually pressed, the elastic clamping ball 234 first retracts and moves out of the first clamping groove 235 under the action of the peripheral wall of the emergency stop lever 232, and then extends outward to be clamped in the second clamping groove 236. At this time, the second magnetic member 233 can adsorb the first magnetic member 213, driving the sliding rod 211 away from the first sensor 22, so that the first sensor 22 detects the sliding rod 211, and then sends a stop command to the execution device through the controller to achieve an emergency stop operation.
[0061] Specifically, the radial hole 237 provided on the mounting seat 231 is used to install the elastic clamping ball 234, that is, to install the second elastic member 2342 and the sphere 2343. In the natural state, the sphere 2343 protrudes outward from the inner peripheral wall of the mounting seat 231, and can form a clamping effect with the first clamping groove 235 or the second clamping groove 236. For the convenience of installation, the plug 2341 is in threaded cooperation with the outer end of the radial hole 237, providing a basis for the installation of the second elastic member 2342, ensuring the effective pushing of the second elastic member 2342 on the sphere 2343, and meeting the good limiting effect.
[0062] In a possible implementation manner, please refer to Figures 1 to 11, a button cylinder base 34 extending into the second chamber 13 is provided through the control box 1.

The third elastic member 312 is used to drive the pressing column 311 to move to the side away from the Hall sensor 33 to the reset state. When it is necessary to control or adjust the speed of the actuating device, the pressing column 311 can be pushed towards the explosion-proof plate 11 side to contract the third elastic member 312. At this time, the pressing column 311 is close to the Hall sensor 33, enabling the Hall sensor 33 to detect the Hall signal and send it to the controller to achieve the speed control of the actuating device.
[0064] In some embodiments, please refer to Figures 1 to 11 , a flange 341 is provided at the outer end of the button cylinder base 34. A fastening nut 342 that can be pressed against the inner wall of the second chamber 13 is threadedly sleeved on the outer periphery of the button cylinder base 34. A limiting ring 343 is provided inside the button cylinder base 34. An inner groove 344 for installing the third elastic member 312 is provided on the outer periphery of the button cylinder base 34. The limiting ring 343 is located within the inner groove 344 and abuts against the third elastic member 312. The side wall of the limiting ring 343 can abut against the side wall of the inner groove 344 to limit the moving range of the pressing column 311.
[0065] In this embodiment, when installing the button cylinder base 34 on the side wall of the control box 1, for the convenience of installation operation, the fastening nut 342 is threadedly engaged with the button cylinder base 34. By screwing the fastening nut 342, the side wall of the control box 1 is effectively clamped by the flange 341 and the fastening nut 342, improving the reliability of the structural installation.
[0066] The inner groove 344 on the outer periphery of the button cylinder base 34 is used to install the third elastic member 312. The inner groove 344 is located at the axial middle of the button cylinder base 34, which is convenient for arranging the third elastic member 312 and forms an abutting effect with the third elastic member 312 through the limiting ring 343.
[0067] On this basis, a plurality of elastic buttons 31 and Hall sensors 33 are respectively provided, and the plurality of elastic buttons 31 and the plurality of Hall sensors 33 are arranged in one-to-one correspondence. To facilitate the installation of the plurality of Hall sensors 33, a PCB board 24 is provided in the first chamber 12.

The plurality of elastic buttons 31 are respectively installed on the side wall of the control box 1 close to the second chamber 13, penetrate the side wall of the control box 1 and extend into the second chamber 13. The elastic buttons 31 and the Hall sensors 33 are arranged in one-to-one correspondence on both sides of the explosion-proof plate 11.
[0068] In a possible implementation manner, please refer to Figures 1 to 11 , the mine explosion-proof man-machine interaction device further includes an enable button device 4. The enable button device 4 includes a fixed seat 41, a rotating rod 42, a torsion spring 43, an extension rod 44, and a second sensor 45. The fixed seat 41 penetrates the side wall of the control box 1 and extends into the first chamber 12. The rotating rod 42 penetrates the fixed seat 41 and is rotationally matched with the fixed seat 41. The extension rod 44 is connected to the inner end of the rotating rod 42 and extends along the radial direction of the rotating rod 42. The extension rod 44 can be rotated by the rotating rod 42 to correspond to the second sensor 45. The second sensor 45 is electrically connected to the controller. The second sensor 45 is used to detect the extension rod 44 to generate a second proximity message and send the second proximity message to the controller. The torsion spring 43 is arranged between the fixed seat 41 and the rotating rod 42 and is used to drive the rotating rod 42 to rotate and reset.
[0069] In this embodiment, by setting the enable button device 4 to feedback a second proximity signal to the controller, after receiving the second proximity signal, the controller starts the Hall sensor 33 according to a preset program, and the control button device 3 can be used for key input to realize the control and adjustment of the actuator. The enable button device 4 can control when the control button device 3 is in an invalid state and when it is in an effective state, which is used to prevent misoperation and ensure that the actuator can be started to work only after all preparatory work is completed.
[0070] Specifically, when the control button device 3 needs to be used, manually drive the rotating rod 42 to rotate, drive the extension rod 44 at the inner end of the rotating rod 42 to rotate to a position corresponding to the second sensor 45. The second sensor 45 generates a second proximity message after detecting the extension rod 44 and sends the second proximity message to the controller. The controller judges that the Hall sensor 33 needs to be started at this time according to a preset program, and then controls the power supply element to be connected to the Hall sensor 33 to ensure the normal operation state of the Hall sensor 33. At this time, the control button device 3 can be used for effective key input to realize the control and adjustment of the actuator.
[0071] In some embodiments, please refer to Figures 1 to 11, a limiting stop platform 412 protruding outwardly is provided at the outer end of the fixed base 41. The limiting stop platform 412 is connected to the side wall of the control box 1 through a second connecting member. A sealing ring 46 capable of abutting against the outer side wall of the control box 1 is embedded on the inner end face of the limiting stop platform 412. A rotating disk 421 embedded in the limiting stop platform 412 is connected to the outer end of the rotating rod 42, and an operation handle 47 extending radially is connected to the outer end face of the rotating disk 421.
[0072] In this embodiment, the fixed base 41 penetrates through the side wall of the control box 1. A limiting stop platform 412 located outside the side wall of the control box 1 is provided at the outer end of the fixed base 41, and the limiting stop platform 412 is connected to the control box 1 through a second connecting member. The sealing performance of the installation position of the fixed base 41 is ensured by embedding the sealing ring 46 on the inner end face of the limiting stop platform 412.
[0073] Meanwhile, a rotating disk 421 is provided at the outer end of the rotating rod 42. The rotating disk 421 is partially embedded in the limiting stop platform 412 and partially exposed outside the limiting stop platform 412, so as to facilitate the installation of the operation handle 47 and facilitate subsequent manual driving of the operation handle 47.
[0074] In some embodiments, please refer to Figures 1 to 11 , an installation disk 422 is sleeved on the inner end of the rotating rod 42. A second spacer sleeve 48 is sleeved on the rotating rod 42 between the installation disk 422 and the fixed base 41. The torsion spring 43 is sleeved on the outer periphery of the second spacer sleeve 48. An axially extending first jack 423 is provided on the outer end face of the installation disk 422, and an axially extending second jack 411 is provided on the inner end face of the fixed base 41. The two ends of the torsion spring 43 are inserted into the first jack 423 and the second jack 411 in a one-to-one correspondence, and the outer extension rod 44 is connected to the outer periphery of the installation disk 422.
[0075] In this embodiment, by providing the installation disk 422 at the inner end of the rotating rod 42, it is convenient to install the outer extension rod 44. The outer extension rod 44 can be threadedly connected to the peripheral wall of the installation disk 422. By sleeving the second spacer sleeve 48 on the outer periphery of the rotating rod 42, an effective interval between the rotating disk 421 and the fixed base 41 is realized, ensuring that the rotating disk 421 and the second sensor 45 are in corresponding positions in the axial direction of the rotating rod 42. Then, when the rotating rod 42 drives the outer extension rod 44 to rotate, the second sensor 45 can effectively detect the outer extension rod 44 and send a second proximity signal to the controller.
[0076] Usage process:
[0077] When adjusting the speed of the actuating device by using the regulating button device 3, first drive the rotating rod 42 to rotate, so that the extension rod 44 at the inner end of the rotating rod 42 rotates to a position corresponding to the second sensor 45. After the second sensor 45 detects the extension rod 44, it generates second proximity information and sends the second proximity information to the controller. The controller determines that the Hall sensor 33 needs to be activated at this time according to the preset program, and then controls the power supply element to be connected to the Hall sensor 33 to ensure the normal operating state of the Hall sensor 33. At this time, effective input is performed by pressing down the pressing rod, and parameters such as the speed of the actuating device are controlled by the pressing force and depth.
[0078] When an emergency stop is required in case of an emergency, press the emergency stop rod 232 to drive the second magnetic member 233 to approach the explosion-proof plate 11 and adsorb the first magnetic member 213. At this time, the elastic ball 234 disengages from the first card slot 235 and is clamped in the second card slot 236. The first magnetic member 213 is used to drive the sliding rod 211 away from the first sensor 22. At this time, the first sensor 22 cannot generate the first proximity signal. The controller determines according to the preset program that it is necessary to control the disconnection of the actuating device, thereby achieving the emergency stop effect.
[0079] The above-mentioned mine explosion-proof man-machine interaction device divides its inner cavity into a first chamber 12 and a second chamber 13 by arranging an explosion-proof plate 11 in the control box 1. The sliding assembly 21 and the first sensor 22 of the emergency stop button device 2 are arranged in the first chamber 12, the emergency stop assembly 23 is arranged in the second chamber 13, the Hall sensor 33 of the regulating button device 3 is arranged in the first chamber 12, and the elastic button 31 and the control magnetic member 32 are arranged in the second chamber 13. The chamber design can be realized to meet the sealing performance of the second chamber 13, thereby ensuring the reliable operation of the electrical components in the first chamber 12, improving the safety and convenience of man-machine interaction. At the same time, by driving the control magnetic member 32 to approach the Hall sensor 33 through the elastic button 31, the controller can receive the Hall signal and control the speed of the actuating device, improving the man-machine interaction performance of the device.
